Pithy a quick recap of the section
Active substance: clomiphene (sometimes written as clomifene). It is commonly prescribed to stimulate ovulation in people with ovulatory disorders.
Common tablet strengths include 25 mg, 50 mg and 100 mg. This medicine is not intended for athletic performance enhancement or routine post-cycle therapy; see the legal entitlement to access and sport guidance for the country of Australia.
What clomiphene does and how things work
Clomiphene is classified as a selective estrogen receptor modulator drug. By blocking estrogen receptors in the hypothalamus and pituitary, it reduces negative feedback from estrogen and leads to increased secretion of follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These hormonal changes can encourage ovarian follicle growth and provoke ovulation, improving the chance of conception for those with absent or irregular ovulation.
Before beginning treatment, make sure you have read the sections on safety and metric monitoring practices and potential secondary effects.
How to administer clomiphene
Swallow tablets with water and follow the exact directions on your prescription. The drug is normally taken at the same time each day for a defined number of days during a menstrual cycle.
- Typical starting plan: one tablet daily for five days, frequently started between cycle day 2 and day 5 as instructed by the clinician.
- Dosing, start day and number of cycles may be adjusted depending on ovulatory response and safety concerns.
- Do not exceed the prescribed dose or continue beyond the recommended course without consulting your prescriber.
Many people who will respond do so within three cycles. Clinicians often limit treatment to around six cycles because benefit tends to decline and cumulative risk increases. For guidance on missed tablets see If you miss taking your tablet.
Safety, mitigating steps and follow-up
- Your clinician may time intercourse, insemination or procedures using urine ovulation kits, blood hormone tests or ultrasound keeping track of metrics to identify response and ovulation.
- Attend appointments so hormone levels and ovarian size can be checked and complications screened for, including ovarian hyperstimulation.
- If you suspect pregnancy, stop treatment and contact your prescriber immediately.
- Clomiphene is a short-term ovulation induction agent and is not recommended for indefinite use.
If you are involved in competitive sport, be aware clomiphene is prohibited under the World Anti-Doping Code; see legal and anti-doping details for Australian requirements.
Who should refrain from using it clomiphene?

- Confirmed pregnancy or while breastfeeding.

- New or worsening visual symptoms, including blurred vision or flashes.
- Ovarian hyperstimulation syndrome (OHSS): severe abdominal or pelvic pain, fast weight gain, marked bloating, persistent nausea or vomiting.
- Signs of pancreatitis: intense abdominal pain that radiates to the back, fever, prolonged vomiting.
Less severe and common effects
- Heat flashes or episodes of flushing.
- Throbbing head pain, lightheadedness or dizziness.
- Tenderness in the breasts or discomfort.

If milder ripple effects are persistent or affecting daily activities, consult your healthcare professional. For advice on keeping the medicine safe see Backup storage space is needed to store more belongings. and disposal policies.
Drug and supplement the mutual influence during contact effects
Always tell your prescriber and pharmacist about all prescription drugs, over-the-counter medicines and herbal or dietary supplements you are taking. Some products can change how clomiphene works or raise risks.
- Herbal remedies sometimes used for fertility such as chasteberry (vitex), black cohosh or blue cohosh.
- Androgen precursors like DHEA (prasterone) which may influence ovarian response.
- Other fertility drugs or hormonal therapies unless coordinated by a fertility specialist.
This is not a complete list; keep an accurate medicine list available for your treating team.
Should you miss a tablet
Should you forget a dose, take it promptly when you remember, provided it is still the same day. If the next scheduled dose is due soon, skip the missed tablet and continue the normal dosing schedule. Do not take two tablets at once to compensate for a i did not take a dose.
